Mark Carlotto

Career and Expertise

Mark Carlotto is an aerospace engineer and Senior Scientist at General Dynamics Mission Systems with over forty years of experience in satellite imaging, remote sensing, and digital image processing. He earned a Ph.D. in Electrical Engineering from Carnegie-Mellon University in 1981, and has specialized in pattern recognition, multisensor object detection, moving target indicator (MTI) radar, terrain and feature extraction, and wide area surveillance systems. His work spans intelligence, surveillance, and reconnaissance (ISR) programs across multiple government and defense contractors.

Space Shuttle Anomalies and STS-48 Analysis

Carlotto gained significant attention in UFO research circles for his rigorous analysis of anomalous objects captured in Space Shuttle video footage, particularly during the STS-48 mission in 1991. The shuttle recorded footage showing unidentified objects moving at extraordinary speeds in the vicinity of the spacecraft. Where many scientists dismissed the phenomena as ice particles ejected by the shuttle's thrusters, Carlotto applied his expertise in digital video analysis to challenge this explanation.

In his paper "Digital Video Analysis Of Anomalous Space Objects," Carlotto calculated that if the objects were at the shuttle's altitude, their implied velocities would be approximately 35 kilometers per second—far exceeding any known human aerospace platform. More critically, Carlotto demonstrated that the shuttle's attitude (orientation) did not change when the objects appeared, undermining the ice particle hypothesis, which would require a thruster firing. His meticulous frame-by-frame analysis and mathematical modeling provided a more parsimonious interpretation than conventional explanations, establishing him as a credible voice on unusual aerial phenomena.

Carlotto also examined STS-80 space shuttle video footage, extending his analysis of orbital anomalies and applying similar rigorous image processing techniques to resolve ambiguities in the record.

Mars and Lunar Research

Beyond UAP studies, Carlotto has investigated anomalous imagery from space missions. He spent considerable effort examining the "Face" and other putative structures in the Cydonia region of Mars, applying advanced image processing to assess whether apparent features were artifacts of pareidolia or potentially intentional constructions. He authored The Martian Enigmas: A Closer Look, examining pyramids and other unusual surface features on Mars with methodological rigor.

He also participated in systematic studies of unusual surface features on the far side of the Moon, bringing the same analytical approach to celestial anomalies. This work, though speculative in some aspects, reflects Carlotto's commitment to applying objective image processing methods to controversial material without predetermined conclusions.

"Not of This World" and Comprehensive UAP Analysis

In 2021, Carlotto published Not of This World: An Emerging Picture of the UFO Phenomenon, representing a synthesis of decades of analysis. The book examines the most compelling historical and contemporary UFO cases on record, including the Gulf Breeze sightings, documented Space Shuttle anomalies, video evidence of crop circles and UAPs, the famous Tic-Tac encounters, and a controversial UFO filmed over the Dome of the Rock in Jerusalem.

Carlotto's methodology emphasizes empirical analysis over speculation. He documents the speed, maneuverability, and apparent defiance of conventional aerodynamics displayed by certain objects. Rather than proposing definitive explanations, he systematically evaluates what the evidence permits us to conclude: some UAPs appear to be genuine phenomena, exceed known aerospace capabilities, behave in ways inconsistent with current physics, and do not conclusively fit extraterrestrial origin—leaving their nature genuinely open.

Contribution to Disclosure

Carlotto has become increasingly visible in UAP discourse, appearing on Coast to Coast AM and other media platforms. He represents a rare category of researcher: a credentialed aerospace engineer with legitimate expertise in satellite imaging and digital analysis who applies his professional toolkit to the UFO question without dismissing it outright or endorsing sensational claims without evidence.

His work bridges the credibility gap—his background in defense contracting and image processing lends authority, while his meticulous analytical approach avoids fringe speculation. In an era of renewed institutional focus on UAPs, Carlotto's capacity to evaluate visual evidence rigorously has become a valuable asset to understanding what genuinely defies conventional explanation.
